<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Similar problem was already reported about a year ago:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="http://mailman.qos.ch/pipermail/logback-user/2011-November/002706.html">http://mailman.qos.ch/pipermail/logback-user/2011-November/002706.html</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I wonder if the problem is going to be fixed in the upcoming version.<o:p></o:p></p>
<p class="MsoNormal">If not, what should be the most simple workaround?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The most disturbing scenario related to this bug is that each value of a sifting attribute creates just one log file.
<o:p></o:p></p>
<p class="MsoNormal">The sift appender configuration is set for compression.<o:p></o:p></p>
<p class="MsoNormal">The bug causes the log file to be left uncompressed, therefore no files are eventually compressed at all.<o:p></o:p></p>
